ee.Geometry.disjoint

当且仅当几何图形不相交时返回 true。

用法返回
Geometry.disjoint(right, maxError, proj)布尔值
参数类型详细信息
此：left几何图形用作运算左操作数的几何图形。
right几何图形用作相应运算的右操作数的几何图形。
maxErrorErrorMargin，默认值：null执行任何必要的重新投影时可容忍的最大误差量。
proj投影，默认值：null执行操作的投影。如果未指定，则操作将在球面坐标系中执行，并且球面上的直线距离将以米为单位。

// Define a Geometry object.
var geometry = ee.Geometry({
  'type': 'Polygon',
  'coordinates':
    [[[-122.081, 37.417],
      [-122.086, 37.421],
      [-122.084, 37.418],
      [-122.089, 37.416]]]
});

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the disjoint method to the Geometry object.
var geometryDisjoint = geometry.disjoint({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('geometry.disjoint(...) =', geometryDisjoint);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(geometry,
             {'color': 'black'},
             'Geometry [black]: geometry');
Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
